The Northeast Organic Dairy Producers Alliance (NODPA) annual field days recently took place in Brattleboro and while this event is a chance for organic dairy producers across the region to get together, many of the topics presented are relevant for any grazing dairy producer, organic or not. One of the great workshops was ‘Top Grazing Mistakes’ presented by three grazing experts – Sarah Flack, organic consultant; Dr. Cindy Daly, California State University; and Kathy Soder, USDA Agricultural Research Station in Pennsylvania. This is a brief excerpt. A complete article from this workshop can be found by clicking HERE.

What are some common mistakes made by dairy grazers?

Inadequately designed system/infrastructure (incorrectly sized paddocks, too few or too many acres, poor grounding for fencing, poor quality land used for grazing)

Pasture nutrition problems (overfeeding protein in the barn and lack of forage quality in the pasture)

Less than ideal grazing management (resulting in overgrazing damage, soil erosion, an increase in weeds, less productive plants, and internal parasite issues)

At this time of the year it is important that pasture plants go into winter with enough energy reserve for next spring. Remember that the plant height you see above the ground is an indicator of the root length below the ground. Sending plants into dormancy with 1 inch of overall height does not give them much energy storage for survival, as these reserves are generally stored in the first 2-4 inches of the plant base. Overtime this can result in weakened plants that die out and decrease the overall density and quality of the pasture. Keeping a higher residual height will allow plants to store more energy and get a robust start in the spring.

So what are some of the practices at this time of the year that can result in overgrazing damage?

Using follower groups that graze close and do not leave enough plant residue.

If you have found yourself doing any of the above, don’t despair! Now is the time to identify any issues and formulate a plan for next year to ensure that pastures remain healthy and productive all season long.
